How hard is it to install the TRD exhaust? do you need to torque wrench it? I was thinking about buying the TRD one for the sweet sound it gives... Just don't want to dealer install it. I have the tools... think it would be an easy install or worth someone else to do it....

Kinda saving up for the greddy or magnaflow catback.... Haven't decided which one I should get yet...

 

Greddy is a axleback... I would suggest going with the creativecompacts.com full stainless steel exhaust with a choice of magnaflow, flowmaster, and borla mufflers. Its only about 100 bucks more than the greddy axle back and its bolt on to the s-pipe... http://www.creativecompacts.com/Merc...SciontCExhaust

Heard good things about it and it has a 12hp and 9tq gain.

 

thanks! any sound clips or anybody here have this setup? which is the better muffler? Trying to stay away from ricey sounds...

 

Well I know there was a article about the dyno there might be a sound clip in there and from what I have been told all three of these have a deep sound to it and not anything ricey... https://www.scionlife.com/forums/vie...485&highlight= thats the topic I was talking about... I would suggest maybe seeing what people say about sound and all and check the muffler makers sites for sound clips of similar engines... sorry I couldnt tell you more.
